Title: Manufacture of mask rom
Inventor: GOTO FUMIHIKO
IPC: H01L27/112
Filed: 1991-01-10
Abstract: PURPOSE:To prevent an increase in a cell size of a mask ROM by implanting ions of the same conductivity type as that of a semiconductor substrate only in a memory array, and setting the peak directly under a field oxide film on the surface of an Si substrate and the peak directly under a gate oxide film in a specific depth from the substrate. CONSTITUTION:While a photoresist film remains on a gate electrode 3 as it is, it is coated with the photoresist, and only a memory array is opened. Baron is implanted, for example, in an amount of one to seven times of thirteenth power of 10 per square cm (1E13-7E13) at 100-200keV of energy. A P-type diffused layer 8 is formed under a gate oxide film 6 and a field oxide film 5 except a part directly under the electrode. In this case, a concentration distribution of the implanted boron is the peak of the order of E18 per square cm on the surface of Si directly under the field oxide film, and it is the peak directly under the gate oxide film in depth of 0.5-1.0mum from the surface of Si.

Filed: 1993-01-07
Abstract: PURPOSE:To obtain a high variable power ratio with simple constitution in a lens for a finite distance in which magnification is not changed even when focusing is done again according to the change of conjugate length. CONSTITUTION:By changing a distance between a front group Fa and a rear group B so that an object comes to the front side focusing position of the Fa, focusing is performed to make an axial luminous flux coming out from the Fa nearly parallel with an optical axis XB. A TF having the Fa and the Fb provided with lens groups having positive power different from each other is attached to a rear group supporting unit TB having the B so that it can freely slide (mc). By allowing the TF to slide, the Fa and the Fb are switched to perform variable power.

Title: Dropout detecting circuit
Inventor: WATANABE HARUHITO
IPC: H04N5/94
Filed: 1990-01-10
Abstract: PURPOSE:To increase the response speed of dropout detection by deciding the rise and fall of a pulse wave outputted from a pulse converting means with the level of an integral wave. CONSTITUTION:When a normal playback FM signal is inputted, this playback FM signal is converted by a pulse wave converting means 1 into a pulse wave, and the integral wave outputted by an integration circuit 3 is reset when the pulse rises and falls, so its level does not reach the reference value of a detection pulse generating means 5. Further, if the input playback FM signal has a dropout, the level of the integral wave exceeds the reference value, so the detection pulse generating means 5 outputs a detection pulse. Thus, the detection pulse is outputted by deciding the rise and fall of the pulse wave outputted by the pulse converting means 1 with the level of the integral wave, so the reference value of the detection pulse generating means 5 is set to increase the response speed of the dropout detection.
